General description
磺酰罗丹明B（SRB）是一种亮粉色氨基甲氧杂蒽类染料。磺酰罗丹明B（SRB）测定被广泛用于 体外 细胞毒性筛选。SRB以化学计量方式与细胞的蛋白质成分结合。因此，从染色细胞中提取的染料量与细胞质量成正比。SRB还可用于细胞密度测定。

The conversion of colloidal drug carriers/polymeric nanoparticles into dry microparticulate powders (e.g., by spray-drying) is a prominent approach to overcome the aerodynamic limitations of these formulations for delivery via inhalation. However, to what extent such nano-embedded microparticles disintegrate into individual/intact

The present study is centered on molecular mechanisms of the cytoprotective effect of geranylgeraniol (GGOH) in skeletal muscle harmed by statin-associated myopathy (SAM). GGOH via autophagy induction was purportedly assumed to prevent skeletal muscle viability impaired by statins, atorvastatin (ATR)
